## Introduction to Cross Section Calculator

When a three-dimensional shape is intersected by a plane, the cross-section is formed, which is a 2-dimensional shape. For example, the cross-section of a cylinder is a circle. The cross-sectional area calculator online calculates the area of this 2-dimensional shape easily.

In geometry, the cross-sectional area of 3D shapes is very important. Because it helps to determine many other physical properties of solid shapes; for example, it helps to find how the water will move in a particular cross section of pipe. So, we introduce a tool that helps you to calculate cross-section of different shapes.

## Formula to Calculate Cross Section in Cross Section Estimator

The cross section is a 2D shape formed when a three-dimensional shape is intersected by a plane. For example, if a sphere is cut in the middle, a circle will be formed.

The formula of a cross section is the total area of any shape. For example the cross section of different shape are:

- Hollow Rectangle:
- $$ cross \;section \;=\; (H \;×\; W) \;-\; \{(W \;-\; 2t_1 ) \;×\; (W \;-\;2t_2 ) \} $$
- Rectangle:
- $$ cross \;section \;=\; W \;×\; H $$
- I Section:
- $$ cross \;section \;=\; 2 \;×\; W \;×\; t_1 \;+\; (H \;-\; 2t_1 ) \;× t_2 $$
- T Section:
- $$ cross \;section \;=\; W \;×\; t_1 \;+\; (H \;-\; t_1 ) \;× t_2 $$
- L Section:
- $$ cross \;section \;=\; W \;×\; t \;+\; (H \;-\; t) \;×\; t $$ $$ Isosceles \;Triangle: \;cross \;section \;=\; 0.5 \;×\; B \;×\; H $$
- Equilateral Triangle:
- $$ cross \;section \;=\; 0.4330 \;×\; L^2 $$
- Circle:
- $$ cross \;section \;=\; 0.25 \;×\; π \;×\; D^2 $$
- Tube:
- $$ cross \;section \;=\; 0.25 \;×\; π \;×\; (D^2 \;-\; (D \;-\; 2 \;×\; t^2 )) $$

These formulas are used in the cross section of the circle calculator to calculate the area of the cross section of any shape. You can select any of them.

## Why use Cross Section Calculus Calculator?

In geometry, the cross-section of a shape is an important concept that helps the students to relate three-dimensional shapes to two-dimensional shapes. They may be able to understand how the intersection of a 3D shape can form a 2D shape. Also, it has many applications in our daily life, such as how the fluid varies with the change in the cross-sectional area of a pipe.

While manually calculating a shape's cross-section, the students may get confused with the formula. It is because different formulas of the cross-section are used for different shapes. Therefore, it would be helpful for you to use this cross section calculator.
